Another data point prior to 2.03 RC2 on a Ruida controller:
- The first PnC alignment produced results maybe 50 mm off the correct position
- The second PnC alignment worked fine
That’s with my usual target marking on a template / fixture used often enough to be familiar with it.
Things I tried:
- Resetting PnC before the first alignment did not help
- Resetting PnC after the failed alignment didn’t matter
- PnC alignments after the second one always worked
So PnC may have something like an uninitialized variable deep inside.
